According to the FreeBSD chflags(1) manpage: The chflags command first appeared in 4.4BSD. Which puts it about seven years after this story.

  "4.4BSD" isn't the same as FreeBSD 4.4, but actually version 4.4 of the original BSD which was released in June 1994.

    OK, eight years, then. The timeline I found gave 1993 for 4.4BSD.
